Webster/Webtec manufactures hydraulic flow controls, pressure control valves and directional control valves for mobile machinery. We offer choices of threading and port size for standard or custom specifications. We offer replacements for Webster gear pumps, Milwaukee cylinders, and Teledyne valves.

The ILFC is a pressure compensated flow control valve (fixed, in-line) with 2 ports. Can be used to maintain the flow rate of hydraulic fluid for operating cylinders and motors at a constant speed.

Fixed priority flow dividers allow you to split a single input flow into a regulated flow and an excess flow. The regulated (Priority) flow can be used to perform the required task while the excess flow which can be routed directly back to the oil reservoir or redirected to drive another system, which can eliminate the need for an additional pump to drive an ancillary system. This is a 3-port flow divider which is pressure compensated and contains an on-board relief valve.

Priority Type Flow Dividers split a single input flow into a Priority flow which is a regulated flow, and a bypass flow, which is excess flow. The excess bypass flow can can be rerouted to the hydraulic fluid reservoir or used to power a second system, which can eliminate the need for a second pump to drive another hydraulic circuit. Easy adjustments to the priority flow can be made visually using a hand dial. Pressure compensation allows both flows (priority and bypass) to be controlled concurrently at their own pressures without changing the flow rate of the priority flow.

A hand dial on this manually-controlled flow divider allows visual adjustments to pre-determined regulated flow to meet pressure requirements. Pressure compensation in the model 2FV2V allows both the regulated flow and bypass (excess) flow to be controlled with a check valve, including an anti-cavitation check valve, which can be routed between the priority and bypass flows. This flow divider is available in a version that can be controlled remotely.

Driven by a 12 VDC (12 - 16 VDC) allows adjustment to the valve from a distant position such as in a heavy machine cab or a remote control panel. Pressure compensation allows both flows to be used at the same time at different pressures without affecting the priority (regulated) rate of flow. Blocking the bypass port while using a relief valve on the inlet line allows you to use the model 2FV2V as a unidirectional two port in line flow control.

A great choice for agricultural and industrial uses, as this remote control flow divider is vibration and contamination resistant and can be powered from a vehicle supply using the on-board 9 - 28 V D.C. supply. Current draw is automatically limited to avoid overheating or motor overload. Model FDM offers a low-cost method of controlling the speed of a hydraulic motor. The regulated (priority) flow port gives an output free of affect by load pressure while the bypass port can be directed to power a secondary hydraulic circuit. Remote control use from up to 130 feet is possible using a potentiometer.

These cast iron and steel Flow Divider-Combiners divide a primary flow into two separate flows which are pressure compensated to maintain the same ratio irregardless of pressure differences between the lines. Return line flows are also held in the same ratio. Lack of aluminum in the construction makes them a good choice for mining and other high-endurance applications.

As an alternative to using a directional control valve, a diverter valve is adequate when there is no need for a neutral position. Flows can be quickly switched between two lines, allowing fast switches from one system to another, or from a system to the reservoir, creating an idling circuit. Flow may be directed two ways: mechanically pushing the spool with spring offset or mechanical push pull operation with an adjustment knob.

Allows the flow to be diverted mechanically by an offset spring pushing the spool. The spool and spring are contained in a sealed housing to prevent environmental corrosion. Available in one spool or two spool versions. The 2-spool version allows you to divert flow from one circuit to another or to a hydraulic fluid reservoir. A wide variety of spool ends and port threading are available.

A rotary spool type directional control valve which contains a rotor that rotates relative to body of the valve. Inlet and outlet ports can be connected in many different flow patterns to control pressurized fluid for start, stop or directional changes. Webster’s flat rotors compensate for valve wear, creating near zero-leak through the life of the valve. Available with 7 different flow patterns, 3 flow ratings and several porting options. These valves may be mounted on a manifold, on a panel or used inline on the hydraulic circuit. Manual control is achieved using ball handles, spring centring and detents.

Durable hydraulic directional control valve used for mobile and industrial systems. Minimal leakage in the spool even under the 3625 psi pressure tank port rating. Methods of operation include lever, cam and pilot (air or oil).

Pressure relief valves protect hydraulic circuits from overload by limiting maximum pressure to a pre-set capacity. The relief pressure setting is set by Webster to the customers specifications within pressures from 290 psi to 3000psi. The fast response of this valve protects the hydraulic circuit from shock and overload or the expansion of thermal fluids. Due to straight-through porting, the valve can be connected inline using a “T” connector. Model RV020 direct acting in-line relief valve is minimally affected by particle contamination
